We are going to put the preloaded sd card in, and we have turned on the monitor. Done! We need to plug in the power supply. We need to plug in the key board and mouse. Done!

Now the moment of truth we need to plug in the raspberry pi! Oh dear we forgot to plug in the hdmi! Oh dear again, we plugged in the hdmi and nothing displayed! So we turned both of them off and on again at the same time (my Dad says this is good IT consultant practice), and it worked!

We typed the user name of Pi, and the password of raspberry. Then Startx to start the desktop, a kind of Linux.
